I was on h+ here where I live in Spokane WA, that's the best I could get.
I'm using a Verizon s7 with a cricket (att) sim card.
Well I rooted with the root on here that don't trip Knox, then I used hidden menus Explorer and selected all lte bands.
After that I rebooted my phone and still stuck on h+ with 3 bars played with it for a hour still h+.
So I decided to go back to stock uprooted just flashed the stock recovery with Oden, once my phone rebooted I had lte 4 bars and faster internet.
Not quite sure what's going on but I like it.
